Hello everyone,
I just wanted to briefly introduce myself and say thank you.
For about a year and a half, I have been a silent reader here to gather inspiration and especially to gain more knowledge about construction technology.
Now a bit about me:
After more than a year of searching for a plot of land, I was able to purchase one from a developer who couldn’t move forward quickly with his plans.
So we found our dream plot (good location, 2500 m² (0.62 acres), slight slope, underground private spring that we have to preserve and are allowed to use).
There was an old house on the property, which we have since demolished.
There is no zoning plan, so §34 applies. During an initial informal inquiry at the building authority, almost everything we planned was rejected.
So we submitted an official preliminary building inquiry, involved the right people, and had lengthy discussions. In the end, we received a positive decision.
Therefore, there is nothing standing in the way of the building permit. The building permit should be granted within the next few weeks as there are no changes from the preliminary inquiry.
My wife (37) and I (36) want to build a Bauhaus-style villa in southern Baden-Württemberg.
It will be constructed from concrete (with core insulation) or in combination with insulated precast elements.
A lot of glass (full-glass system), textile shading, KNX, fast network both wired and wireless, strong mechanical ventilation with additional cooling coils, stainless steel pool, large cistern, and more.
The electrical planning must be 100% spot on since it’s almost impossible to make changes afterward.
Since I am friends with an architect from a larger firm, it was clear which route we would take. Such a house can basically only be realized with an architect.
I also personally know the electrician and KNX system integrator, as well as the owners and work approach of the heating, plumbing, and ventilation companies involved.
Some trades have already been contracted, and part of the equipment has already been ordered.
I’m really looking forward to getting started and to the final result. The goal is to move in by the end of 2019.
Once again, many thanks for the information I have received from you so far.
If you have any questions, just let me know.
Attached is the design, though not the final version. There have been a few minor changes.
Greetings from Swabia

Could you please explain that point in more detail? It will be similar for us, especially the issue with the building line. Thanks!This certainly varies from state to state and city to city. We were granted the building line because the layout behind our plot is similar. The cube appears to float and leaves space at the front...
You will need an architect and a building law expert who is best well connected. With a small plot, it can be difficult to argue for deviations of, for example, 3 meters (10 feet) to the rear.
Keep the discussion open and be ready to make compromises, such as slightly shifting the building line but accepting the roof shape in return...

hampshire3 Aug 2019 09:56I had the same experience. I was allowed to exceed the building line by one meter and build one meter wider than planned. A carport was approved outside the building envelope. The architect and design convinced the building authority. There was no major discussion regarding our polite request.
This week, along with the building permit / planning permission application, we also submitted a waiver request for boundary encroachment: 1 meter (3.3 feet) for the house and 1.5 meters (5 feet) for the garage. However, several discussions between the architect and the building authority took place before the application.
If I remember correctly, the fee for the waiver request is about 1,300 euros (approximately) in total (but nothing has been approved yet) and is calculated based on the building type and cubic meters. The rate seems to vary from municipality to municipality. For us, it was worth it.

Bauherr am L8 Aug 2019 17:42This house is going to be amazing, great and impressive that you are openly sharing the process. That’s definitely quite rare in this category.
One question regarding
Does this mean the house is being built using precast concrete elements? Also for the areas in contact with the ground? I find this very interesting. Could you please explain the reasons and the construction method in more detail, and also which company manufactures the concrete parts?

Most of the house is made from precast concrete elements.
We definitely wanted a concrete look.
Originally, we considered cast-in-place concrete. However, that is quite expensive and also problematic in terms of insulation values. Additionally, there were issues related to our windows.
We would have needed walls almost 1.5 meters (5 feet) thick, etc.
The second idea was insulated sandwich panels. That didn’t work either because of the windows.
So now we have a combination of cavity walls (which will be filled on site) and, in some areas, cast-in-place concrete. Basically like the retaining wall that is already standing. It also still needs to be filled.
Outside, there is a ventilated cladding system with insulation and aluminum composite panels.
